HORTICULTURE

Detailed explanation-1: -Root hairs form in the zone of differentiation and this is where they begin to poke out into the soil to absorb water and mineral nutrients. Root hairs greatly increase the root surface area and therefore increase the ability of a plant to absorb water and nutrients.

Detailed explanation-2: -The root system is usually extensive and has root hairs which help increase the surface area for water absorption. Water enters the root hair cells and then moves from cell to cell till it reaches the root cortex. It goes on to the xylem vessels to be transported to the leaves.

Detailed explanation-3: -Fibrous root systems consist of many fine hairlike roots that form a thick mat below the surface. These root systems are very effective at water and mineral absorption, as well as plant stabilization.
